IMPROVEMENT IN BURlAL-CASKETS.

Specification forming part of Letters Patent No. 205,555, dated July 2, 1878; application filed April 30, 1878.

To all whom it may concern:

Be it known that I, OSMOND M. JOHNSTON, of Brownsville, in the county of Fayette and State of Pennsylvania, have invented a new and Improved Burial-Gasket or Coffin, of which the following is a specification Figure 1 is a side elevation, partly in section. Fig. 2 is a plan view with a portion of the cover removed. Fig. 3 is an inverted plan view of the cover.

Similar letters of reference indicate correspondin g parts.

My invention consists in a casket or coffin formed of potters clay, and having transverse and longitudinal ribs formed on the inner surface of the top, sides, and bottom.

In the drawing, A is the body, and B the cover, of the casket or coffin, which are externally of the ordinary form, but are provided internally with strengthening-ribs, which not only strengthen the casket or coffin when done, but also prevent the sides, cover, and bottom from warpingin the process of baking. The ribs are formed on the inner surface as the clay is molded.

1n the present case the bottom 0 has transverse semi-cylindrical ribs a and longitudinal ribs 1), of the same form, and the sides have vertical ribs 0, which are also semi-cylindrical.

The cover B, which is paneled, is provided with transverse ribs d e, that correspond in form to the other ribs, and tend to strengthen it and prevent it from warping. I

By my improvement the casket or coffin is rendered strong and light, and it preserves its shape during the process of baking, so that there is little or no loss from warping in the process of manufacture.

It is obvious that ribs may be formed on the outside of the casket with the same advantage.

I do not broadly claim the casket made from potters clay 5 but What I claim, and desire to secure by Letters Patent, is

A burial-casket made of potters clay, and having internal ribs, substantially as shown and described.
